It’s so enjoyable to finally see an really professional made tutorial. Not only that but also the video is top class. All the kudos to you Sir. Highly recommended.

Thanks for making this video. I was looking for PWM tutorials mainly for sound processing but this was incredibly informative. Also I didn't realise that PCB's were so cheap to buy, I'll be using those a lot more in my circwits. Many thanks buddy

This video is very beautifully completed. Not only great explanation about PWM, but also how to create fully working circuit as well as smooth ads integration. Bonus that nice flow motion time-lapse 👏

I learned about pwm from this video and I hardly know anything about electronics. It's thanks to your very good demonstrations. Keep up the work please.

Seeing the representation on the oscilloscope really helped me understand how PWM works. Thanks for the great demonstrations

I spent 30 years designing PCB's, beginning with hand taped boards on mylar sheets all the way up to sophisticate auto-routers. Still, It's amazing how far things have come. $2 boards, crazy!

I assembled my first pwm motor controller using assemblies from Amazon. It worked perfectly and allowed my old VW to have AC w/o fixing the defective computer. Thx!

Very great teacher, you are, Master of the 555. No joke, I learned why we use Pulse Width Modulation with you here and what uses it has. It cleverly limits sordid power dissipation too! Perfect crash course on the 555. Thanks Master. Thanks a lot.

First time seeing that $30 oscilloscope(Amazon diy oscilloscope) used. Now i'm ordering it. Thanks for using it, and making this video.

Seriously amazing video with a lot of great info. Thank you so much for making this video. I can't wait make this circuit for myself.

You just make the thing enjoy itself. Amazing tutorial! keep this productivity.

Good job informing, presenting, explaining and linking with sponsors. Thanks.

I am not an electronic/electrician guy, but your way of explaining is very good. Thanks for your effort 👌

Really a good video, simple to understand and clean. Thank you for this tutorial.

Beautifully presented and very clearly explained. Thank you for taking the time and effort to create this video.

Excellent video! Very informative, excellent production quality and to the point. Thanks!

pretty late - but I like the way you chose for the PWM explanation. and I like this oscilloscope which I think I will buy to see these pulses and check things like servos. Was not aware of PWM as servocontrol ... Therefore I will walk through the list of videos on your channel to find more explanations I might need later ... really great work this video to do it 3 times from breadbord to pin board to pcb

Sir,you perfectly explained the pwm,thanks a lot.

I like that you showed a website to design and build a pro grade board very nice.

I love your channel i learned so ooooo much. I don't hot the like button a lot but i felt compelled to. You are honestly so smart and i look up to you because of videos like this.

This was awesome and engaging! Keep them coming!

i have a PWN controller in my house that i use to test DC motors, now i finally know how it works.

Thanks for the video. Was looking for tutorials on PWM for some projects related to RC cars and in general controlling of Motors using PWM.

You are talent, and thx for help in PWM Understanding, this practical explanation helps a lot. 🤩🤩

Great video keep up the good work. Helped me understand PWM.

Really great content with quality and knowledge. Thanks for sharing your knowledge and creativity.

Thank you so much for making such a wonderful informative content. I really appreciate your effort. Keep making such videos.

one of the best videos of this subject that i have seen

the presentation and explanations are very nice and clear, thanks for such an video.

Thanks for teaching. Doing electronics is an ART.

Wow incredible video! Thank you so much for making this!

Good because speed of words expelling is easy to understand by even non english mothertong peoples. Well planned explanation and good heading

nice, im gonna be using this to control the speed of a motor in a smart incubator i´m building. Thanks!

Great video! Very informative and easy for a noob like me to comprehend :)

very helpful video to explain the concept in a visual way cheers

From a novice, thank you so much for the tutorial.

4:00 for led's we dont use pwm to decrease voltage, same goes for majority of usecases, pwm is mainly use for quick on/off while still having high voltage, just not nonstop, for led or dc motors you need to have high enough voltage to run them at all, so you use time, not voltage to control brightness or speed. Pwm is used for decreasing voltage only for variable voltage output and you need to have inductors and caps on the output, for example VRM for cpu/gpu in pc.

Great video. This was extremely helpful!

Very good video "keep them coming"

Superb explanation and demonstration views, and animations. Congratulations! I think this is the best video in these regards. I will thumbs up, and subscribe.

أشكرك وأقدر مجهودك ، تحياتي لك من تركيا .

Thank you sir very well explained so simple but great impact

really hope for other electronic video like this

Very professional video. Good job!

Amazing job, amazing teach, amazing video. Thanks to you man.

Great job on the animations!

Thanks for sharing this useful information.

Thanks for your explaning

perfect explanation and excellent work

This is an AMAZING tutorial!!!!!!

That's a great work of yours sir, but can I ask if how did you design the circuit I mean how did you know the exact value of components to use also how did you know to connect them properly in the schematic, please let me know because I want to learn to design electronic circuits on my own, thank you

Great and very educative and entertaining.God bless you

Thanks mate, very useful video!!!

excellent video, thanks for your time

You deserve more than a like for this great work 👍

thank you for the high quality content

Excellent video!

Awesome way to explain it ....thanks

Great video information 👍 Thank you for sharing your knowledge ❤🇵🇭

Great explanation. Thank you

nice work on the circwits

I think the analysis in 3:30 is very important. Sometimes you have no option other than use a potenciometer, so sometimes when you work mainly with situations you can't use a PWM, you forget this aspect of the PWM when you have the opportunity to use it 5:16

thanks for making this video bro

The outrun music is perfect.

how can we add ,different type of frequency for getting different type of pwm signal by using Arduino?

Very helpful. Would you happen to know what the high and low voltages are on the PWM signals used in Volvos to control the AC Blower Motor? Say in a 2008 XC90 there are 2 small awg conductors that must be used for the PWM signals and there are 2 Heavier Wires each 10 Gauge Red and Black that provide power from hot to chasis ground controlled by the power transistor and PWM Duty Cycle Signals. Most literature still uses the term "Resistor Module' that controls AC fan motor speed but that is just from days of the old technology to control fan speeds. The fan control module must be a power transistor instead that is is controlled by the 2 small conductors Blue & Yellow coming from the climate control module.

Excellent I understand now - as promised

Hi, is there a wiring diagram of the Arduino that you created near the end , I'm currently running a project , however, I have to show examples of each a mechatronic motor, a plc motor and a pmw, that one you placed at the end is perfect for what I need to do, many thanks, great video 👍

Very good video, thanks.

Nice video! What program did you use to simulate the circuit diagram?

Thank you it was a very good circuit. I have question what's the max voltage and amper ?

Do u 've any suggestion for higher frequency about 1Mhz.. while looking through a camera my flood lights are flickering in full efficiency

Nice work

amazing channel, thanks!

great explanation

Hi from Argentina, excellent video, i have a question, can i use this pwm to control volume of alarm siren 12v?

Very optimum and impressive making.

Excellent video. How did you learn to design PCBs on Easyeda? There are no good videos from them. Also looking for components and picking the correct size, for example to fit a POTs pins is like searching through a jungle. How do you determine correct pin spacing on components contributed by other people? Any helpful tip is much appreciated. Keep up the great work. Thank you.

hi , thanks for the video , found the link from easyeda

Great quality training videoI could understand ....

Good video! Can I use an LED instead of a motor? If so, can I consider it as a constant current driver or voltage driver? Thanks

that was too good explanation and showed it so easily

Thank you very much for you. god bless you!

Do i have to use pwn for a brushless motor?

Can I use that board to control amperage on another brushless motor controller

Excellent . Thanks

Woooow amazing 👍🏻🤩

How reliable would this pwm circuit be to control the speed of the fan?

Great explanation

Awesome video

Good work

Do you lose torque with lower speed as much as you would if you were to use a simple potentiometer to lower the voltage?

Good work .

Great video thanks

Hello I have unusual question wuld that circuet work with pick up coils found in distributors? I have for days problems finding corect circuet to interupt pick up coils going to ignition module . So any help please? Basicaly I need circuet that can control pick up coils phase shift them or controling pulse generators pulse duration

Very inspiring!

Sir please can you answer me a simple dc motor can move by using servo tester and MOSFET?😊

0:55 Just for clarification, the simplest circuit is a toss up between an open circuit and short circuit.

Can a rc receiver send Pwm signal into your circuit to turn on/off led

Good job and a nice implementation. I'm gonna to fo Mosfet driver and I want a high frequency typically like 50khertz. Can the Arduino give me these values or I have to implement a timer 555 and deal with resistors and capacitors to have these frequencies
